IMPROVEMENT IN CAR AXLE-BOXES.

Specification forming part of Letters Patent No. 149,273, dated March31,1874.; application liled March 27, 1873.

To ail-'whom it may concern:

` this specification.

In the drawings, Figure l is a vertical longitudinal section of myinvention. Fig. 2 isa vertical transverse section ot' the same; and Fig.3 is a vertical transverse section illustrating modification.

My invention has reference to the axleboxes ot' steam and horserailway-cars; and it consists in providing said boxes with an oilchamberlocated in theI top of the box, said chamber being cast with and forminga part of the box, and being formed with wick-tubes rising from its,door and registering with suitable openings in the wedge and bearing, orin the latter alone, for conveying oil to the journal. Itfnrtherconsists in the peculiar construction of the box-lid, which isbent in such form that when opened itgives access both to theoil-chamber above the axle and the chamber beneath the same, ashereinafter described.

Referring to the drawing, A shows an axleboX, the upper part otwhich isformed ot' an oil-chamber, B, divided inti two compartments by thepartition C and having communication by means of openiigs c c, saidpartition being provided for the purpose ot' giving the necessarystrength to support the weight of the car. b bare wick-tubes rising fromthe door of the chamber B and registering with openings in the bearingE, said openings being designed to be filled with wick, felt, or

other suitable porous material. Instead of making' the chamber with aplain iat i'loor, as

described, it may have wings, as shown at e c in Fig. 3, which wouldthus increase its holding capacity. F shows the lid, hinged on top ot'the box at f and lient as seen atf, having thus an upper horizontalportion, f2, and a lower inclined portion, f.

The advantage of this construction over a hollow bearing or wedge isthat it will contain a much larger body ot' oil than either ot' them.Itis also more economical than a hollow bearing, which, being formed ot'brass, costs a considerable sum. NVith this box the ordinaryr solidbrass bear-iii g may be. used, suitable holes being drilled for thepassage ot' the oil. The construction ot' the lid permits easy access toboth the oil-chamber above the bearing and the usual chamber [I beneaththe axle.

I claiml. The lid F bent at-f1 to form an upper horizontal portion, f2,and a lower inclined portion, f, in combination with an axle-box havingan oil-clianiber at the top and an opening in front, both ot' which saidlid closes, all substantially as shown and described.

2. The axle-box A cast with the oil-chamber B, having wick-tubes, saidchamber heilig divided into two compartments by means ot' the partition(l, having the channels c, all sub stantially as and for the purposedescribed.

3. 'llie axle-box cast with an oil-chamber in the top and havingwick-tubes b and side depressions c, substantially as shown anddescribed.

In testimony that I claim the foregoing I have hereunto set my hand this17th day ot' March, 1873.
